The ligands of (E)-bis(p-3-nitrobenzoic acid) vinyl (C16H10N2O8) were synthesized in three steps, and then the MOF-Zn2(EBNB)2(BPY)2·2H2O was synthesized by solvothermal method. This structure was characterized by X-ray single crystal diffraction, SEM and TG. The drug loading and in vitro release of Zn2(EBNB)2(BPY)2·2H2O were also studied with Methadone as model drug. The result shows that the highest loading amount of Zn2(EBNB)2(BPY)2·2H2O to Methadone was 0.256 g/g, and the drug delivery system was a two-phase mode. The results of in vitro cytotoxicity test shows that Zn2(EBNB)2(BPY)2·2H2O has good biocompatibility.

One three-dimensional structure material {(ZnBTC)(CH3)2NH2.DMF}n (BTC = benzene-1,3,5-tricarbo MOF porosity xylic acid) with a novel hollow-basket spheral cumulate structure was synthesized and characterized. This material crystallizes in Monoclinic, space group P2(1)/n. The thermogravimetric analysis shows that the material can be stabilized to 400°C and the skeleton collapsed occurred in about 360~520°C. The maximum nitrogen adsorption capacity of this material was 10cc/g, the methane adsorption was 1.80 mmol/g under the pressure of 10 bar and the pore structure parameters were measured subsequently.

The ligands of (E)-bis(p-3-nitrobenzoic acid) vinyl (C16H10N2O8) were synthesized in three steps, and then the MOF-Zn2(EBNB)2(BPY)2·2H2O was synthesized by solvothermal method. This structure was characterized by X-ray single crystal diffraction, SEM and TG. The pesticide loading and release of Zn2(EBNB)2(BPY)2·2H2O were also studied with jinggangmycin and avermectin as model pesticides, representing water-soluble and oil-soluble pesticides respectively. The results show that the highest loading amount of Zn2(EBNB)2(BPY)2·2H2O to jinggangmycin and avermectin was 0.346 g/g and 0.304 g/g. The pesticide delivery system was a two-phase mode and the cumulative release of jinggangmycin was 76.8%, of avermectin was 73.8% in 84 h, which show obvious slow release effect. Meanwhile, compared with the control group of jinggangmycin·avermectin wettable powder, the sustained-release system has better effect on the inhibition of rhizoctonia graminearum.
